Suppose you have a 1020 steel plate in axial loading, with an static axial F of 30000 lbf. The plate is 4" thick, 2" high, and 6" length. The hole is in the center of the plate, and is 1/4“ in diameter. The plate is at room temperature, and the strain at fracture is greater than ɛf > 0.1. If Sy = 80 ksi and Sut = 100 ksi, calculate the highest stress in the plate. Plate dimensions: 6.00" 2.00" 1.00" 0.25" 3.00"

Question
Suppose
you have a 1020 steel
plate in axial
loading,
with an static axial F
of 30000 lbf. The
plate is 4" thick, 2" high, and 6" length. The hole is in the center of the
plate, and is 1/4“ in diameter. The
plate is at room temperature, and the strain at fracture is greater than ɛf > 0.1. If Sy = 80 ksi and Sut =
100 ksi,
calculate the highest stress in the plate.
